Split ihipCtx_t into ihipCtx_t and ihipDevice_t .

소스 검색 
Major change to existing code base.
    Ctx holds streams, enables peers, and flags.
    Device holds accelerator, hsa-agent, device props.

Add hipCtx_t.

Add peer APIs that accept hipCtx_t (in addition to deviceId)

Compiles and passes directed tests.
